Describe the normal ranges for pH and carbon dioxide in the blood.
Blood has a normal pH range of 7.35 to 7.45. This means that blood is naturally slightly alkaline or basic.
The normal range for CO2 is 23 to 29 mEq/L (milliequivalent units per liter of blood).
And the normal arterial pressure of CO2 is 35-40 mm Hg.
The blood test often measures blood pH along with CO2 levels to further determine the cause of your symptoms. Blood pH is a measurement of acidity or alkalinity. Decreased pH leads to acidosis and increased pH leads to alkalosis.
